We all know that people are overburdened with work and pressure these days and often forget to smile, but this must not happen. You must know that it is your smile that can make you happy all day long. You can spend a lot of time and money for your make over, but nothing is possible without showing you 100 watt smile.
The shape of your smile matters in making you happy. The shape changes the blood flow to the brain and actually makes you feel happier. The fact that smiling itself boosts your mood has a further positive impact because smiling has a contagious effect. When you smile at others, you are likely to get a smile back which increases your confidence and makes you feel happy.
If you think that it is just the eyes that speak of you, then you are wrong because your smile also talks about you and speaks of your feelings. Having a radiant smile sends a positive message to those around you. It tells people that you are happy to be in their presence, creating an optimistic feeling in others.
It is your smile that shows confidence. If you show your teeth, you reflect confidence and radiance.
